Rotary Vane

Cooper Power Tools offers two types of rotary vane air motors: the large Gardner-Denver MR series (1.0 - 7.5 HP), and small to medium sizes (0.14 - 2.3 HP) in the Dotco, Buckeye, and Gardner-Denver product lines. These rotary vane pneumatic motors feature durable construction with precision heavy-duty bearings throughout, and multiple blade rotors for smooth power. Choose from a wide range of speeds and torques, as well as options related to foot, face, or flange mounting. Options for rotary vane motors include reversible or non-reversible motors, and side or rear exhaust, and threaded or keyed spindles.

To operate properly, the following must be taken into consideration when specifying an air motor for an application

Air pressure, psig or bars, at the motor location

The air line pipe size must be sufficient to supply the volume, cfm or m3/min, of air required to operate the motor

For most plant air systems the pressure varies during the day. The motor should be sized according to the minimum air pressure you normally have available.

For reversible air motors, a four-way control valve is recommended to obtain forward and reverse. For one direction of rotation only, a one-way valve may be used.
